Frequently asked questions
How do you decide between a repair, an overhaul, and a rebuild?
We measure wear with compression, blowby, and oil analysis. Isolated failures get targeted repairs, while widespread wear justifies an in-frame overhaul or full rebuild.
Do you diagnose before quoting?
Yes. We confirm root cause with diagnostics so the estimate reflects the actual failure, not a guess.
